MAINTENANCE
38 – English
”Air Injection” centrifugal cleaning
Centrifugal cleaning means the following: All air to the
carburetor passes through the starter. Dirt and dust is
pushed out by the cooling fan.
IMPORTANT! In order to maintain operation of the
centrifugal cleaning system it m
ust be regularly maintained.
Clean the air intake to the starter, the fins on the flywheel, the
space around the flywheel, inlet pipe and carburetor
compartment.
Heated handles
(346XPG, 353G)
On models with the model code XPG/G both the front handle
bar and the rear handle are equipped with electrical heating
coils. These are supplied with electricity from a generator
built into the chain saw.
When the switch is pushed upwards, the heat is switched on.
When the switch is pushed do
wnwards, the heat is switched
off.
Electrical carburetor heating
(346XPG, 353G)
If this chain saw is marked with Carburetor Heating then it is
equipped with an electrically heated carburettor. The
electrical heating prevents icing in the carburettor. A
thermostat regulates heating so that the carburettor always
has the correct working temperature.
Winter use
Running problems can occur when using the machine in the
cold and snowy conditions caused by:
• Too low engine temperature.
• Icing of the air filter and carburetor.
Special measures are therefore often required:
• Partly mask the air inlet on the starter to increase the
w
or
king temperature of the engine.
• Preheat the intake air to the carburetor by using the heat
from the cylinder.
Temperature 0°°
°°
C (32°°
°°
F) or colder:
A special winter kit, including necessary parts and assembly
instructions, is available for using the machine in cold
temperatures.
345e: Before usage a hole is made in the cylinder cover and
a winter flap is fitted (see illustration below).
346XP, 353: The cylinder cover is designed so it can be
adjusted for running in cold weather.
Twist the winter flap so that preheated air from the cylinder
can pass into the carburetor space pre
venting icing of the air
filter, etc.
For temperatures below -5
°C (23°F) and/or in snow
conditions there is also:
• a special cover (A) for the starter housing
• a winter plug (B) for the air nozzle that is fitted as shown.
These reduce the flow of cooling air and prevent large
amounts of snow from being suc
ked into the carburetor
space.
For further information see assembly instructions for the
winter kit.
CAUTION! When the winter plug is fitted the winter flap must
be open!
IMPORTANT! If the temperature rises above -5°C (23°F) or
0
°C (32°F) respectively the machine MUST be restored to
its normal set-up. Otherwise there is a risk of overheating,
which can cause severe engine damage.
